Minimal Bathrooms
If you think your new apartment’s bathroom is small, then wait until you hear about submarine bathrooms. Given that submarines have large pieces of equipment and machines taking up space inside them, there is very little room to move around.
From this photo, you can deduce that the bathrooms on submarines are relatively tiny, which often leads to feeling claustrophobic while using the facilities. Now, envision that but with many crew members and you have complete mayhem. Can you imagine having to share one bathroom with many people for a couple of months? Not fun.
